Twenty years a Great Wall guardian

Li Shixiang rests while patrolling an ancient town in Haiyuan County, northwest China's Ningxia Hui Autonomous Region, Aug. 12, 2021. Li Shixiang, 45, lives in Haiyuan County in Ningxia and has been engaged in the research and protection of the Great Wall for over 15 years. When Li was a middle school student, he lived near an ancient town. The ancient walls and scattered ancient coins interested him and he visited the town with his friends every weekend.
